Hello, I just got an evo V , I experience a problem and I cannot identify the causes so please the help of anyone experienced will be greatly appreciated**
1- Irregular Engine sound which causes vibration inside the car
2- When I start walking with the car on low RPMs (0-2) I slightly press the gas pedal and fix the pedal on that slight press, the car starts jerking severely as if i'm pushing and pulling my feet on and off the pedal. It was fine on high RPMs until a couple of days it started to jerk on higher RPMs (3-7) HINT: when I remove the mass airflow sensor's plug and drive the car , these symptoms disappear , I replaced it with another (thinking this would fix the problem) but nothing changed.
3-While accelerating when I push my feet on the pedal (RPM should rise) it rises and the car accelerates, however if i pulled my feet and pushed it quickly the car stops responding and RPM falls to near idle without me removing my feet from the pedal !!
4- Yesterday I tried driving the car on high rpms after i tried it , the engine's sound changed as if something's really wrong so I stopped and pushed the gas to check the sound clearly I discovered that the RPM won't rise after 3(000) and the car became extremely weak as if i'm driving a 10 HP car !!!!!
5-Before this, hearing fuel bombs from time to time was normal
Thanks for reading , your help will be sincerely appreciated !!!
